My firemouth was found this morning on his side. Still alive but cant stay upright. I moved it to another tank, added a heater, filter and powerhead. Seems the fish is trying to fight but I feel it may die. I dont know what to do for it. It mostly lays on its side or back, then sometimes it gets upright and sometimes it trys to swim but it swims really disorientated and darts around mostly, then back on its side or back. I also noticed its fins are a little ragged. Any suggestions? Thx
